With this, Postfix 2.6 will be able to do EECDH key exchange and ECDSA authentication. cool. what does it talk to? if it only talks to postfix, I would call that a terribly good first step and a wonderful basis for someone to explore ECC/TLS interoperability with Sendmail and Exchange. It may be some time before the first public CA signs an ECDSA cert (especially with an ECDSA CA cert). agreed. the vendors don't seem to care. However, with private-label CAs, or bilateral key exchange, the EC support in OpenSSL works now when both the server and client run OpenSSL. TLS support in email systems with no public certificate system to support it will be at least as sketchy as the current sorry state of affairs where nobody cares about the signature on their RSA certs :-( Hopefully the CA engine vendors (that'd be Oracle, Entrust, Microsoft, and others...) will wake up and figure this out. I don't have access to other implementations for interop testing. that's ok. someday someone like me will do a product review of someone's ECC/TLS/SMTP product and make sure it gets tested... if we're all really lucky some commercial enterprise will make sure it gets tested and the feedback is properly available in the open source community. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]

Re: About ECC patent and OpenSSL ECC code
As far as I'm concerned, ECC isn't a legitimate public key algorithm for enterprise use at this time because you can't buy a cert from a CA listed in a major browser where the cert uses ECC. Also, those of use who went through the onerous and in the end counterproductive experience of licensing RSA can tell you that the give me money or I'll sue you business model got old after a while. I'm not a lawyer but I do have to give CTO-class advice and, assuming you've found a business case for ECC, I always recommend people do a build/buy/license/let them threaten litigation we don't care comparison before entering into not-obviously-useful patent licensing deals. So I recommending paying a lawyer to determine if you even care about some vendor's alleged patent portfolio. The fact ECC is in OpenSSL is cute. In the oh, isn't that cool, they implement IDEA, RC-6, and ECC kind of exotic crypto side-show kind of way. It's not part of openssl, the open source TLS/SSL implementation you can use in the real world any more than any other non-IE/Firefox-supported TLS ciphersuite combination would be. I'd be more impressed with the NSA/Certicom deal if I could find any public evidence there's any PKI anywhere using ECC for a US .gov. As it is this just ends up looking like another exotic military purchase not related to the enterprise world.

However, unless they were actually using the patent docs during implementation, I doubt that this would be the case. 3) patents on ECC techniques Now these are the ones you can find in the implementation of OpenSSL. There are two main ones here – point compression and MQV. Point compression reduces the size of an ECC public key, but ECC keys are much smaller than RSA keys even without it, so this one can be avoided. MQV is a key exchange technique. It also can be avoided by using ECDH. NSA licensed 26 Certicom patents (which includes MQV and point compression) for use in government applications with prime modulus curves greater than 255.

DSA cert and one ECDSA cert. The code for adding more certs is the

Which cipher-suite will actually be used by the client and server depends
on the client's and server's cipherlist, and whether the server takes

ipv6 support in 0.9.8g
I am trying to use openssl to exercise some ipv6-literate networking gear. It's not working, and I am investigating what I'm doing wrong. here's what I think I see. note - I did some bit of poking on the list and I didn't see anything but a vaguely recent discussion about a proposed v6 patch and some mention of using something from the live source tree instead. (and if you too hit this in three years because v6 is still not deployed, read past this in the mailing list in case some wise soul corrects me...) to test in v4, I do this: 0. set up the network. if you think about linux and two boxes wired together it's like this: ifconfig eth0 10.0.0.1 netmask 255.255.255.0 on the server ifconfig eth0 10.0.0.2 netmask 255.255.255.0 on the client 1. use apps/CA.pl, etc. to spin a CA and then a server certificate 2. use openssl s_server, with the cert spun in step 1, 3. use openssl s_client -connect server to connect to the server started in step 2. this gives me a whole http-over-ssl sequence, that I can tweak to check sloppy vendors for enabling sslv2, etc. with ipv6, I want to do the same thing: 0. ifconfig eth0 add 2001:0df8::1/32 on the server ifconfig eth0 add 2001:0df8::2/32 on the client 1. cert generation is the same 2. openssl s_server. ... now it gets to be a problem. openssl s_server doesn't seem to put up a tcp listen on the ipv6 address. and, openssl s_client doesn't seem to parse ipv6 addresses like 2001:0df8::1 or [2001:0df8::1] or an entry in /etc/hosts or an entry in the dns that's an record. so here's some questions... 1. does the openssl tool work with ipv6? for listening or for calling? is there an alternate test tool in the openssl distro? 2. how are you supposed to do the ipv6 reverse lookup stuff to check a server certificate for verification? how is that tested (assuming it's there)? I know there's some v6 support in the PKIX certificate parsing area but is it supported in (BIO? where networking things happen.) 3. assuming for the moment I am correct and there is only partial v6 support, are there any other folks out there wishing to use TLS over ipv6? 4. I could use curl or wget or lynx or firefox or something to exercise tls-over-ipv6 connections.

The only thing done with the cryptoswift is the RSA key calculation. All others things are done by your CPU(s) So what about the actual data encryption/decryption? If the system handles this, the potential gains are pretty high for a powerful system. How much of the actual handshake has to be done on the card? I know this can be done with a separate appliance, like the Intel 7115 (which takes the fun of actually implementing a solution away), but these are overly expensive, and make relational performance measurements pretty complicated in many configurations. There many other appliance CiberIQ, Alteon ... cryptoswift is very expensive , The sonicwall card seems to be nice (RSA, 3DES, DES, ARC[24], SHA1, MD5) and cheap, but i didn't have the opportunity to make some tests I've heard of the CyberIQ. I've also heard that their numbers were cooked a little more than most of the providers. I'm sure we will wind up validating a number of options. Enough rambling about this though. Now you have a context for my original question: can the OpenSSL engine spill extra SSL sessions over to the system cpu? When I run some test with heavy load of ssl transaction with the cryptoswift 200, the 2 cpus (p3-700) was 0% idle. But i don't know if some keys calculation has been done by the cpus Interesting. Was your system responsible for anything else (ie, a ftp server, etc.)? Were you using Apache in the back end? Our system is pretty streamlined, we have left out a lot of the 'bells and whistles' found in Apache, so we can handle a lot more throughput. We can serve 500+ objects on a clear connection from a Netra 440, where our experience shows Apache at less than half this for the same system. Purely CPU bound on the server side. Client side (separate system) is I/O bound until you start fetching on a secure connection. Maybe we want to see how one of these cards performs there? Thanks for your feedback.

the hardware vendors claim speeds of 300-2000 RSA operations per second. One would like to think that, with that sort of hardware, one can productively offload even an 800 MHZ CPU.

mechanical extraction of roots from netscape?

netscape/iplanet server certificate and root with openssl
I want to create a root certificate and a server certificate with openssl. These will be used with iPlanet Web Server 4.1 I created the root, using CA.pl. I then created a certificate request with the web server, signed and installed the root and the server certificate. This doesn't work. The web server refuses to start. I see these problems: in the log it claims there is a missing attribute field in the server sert (errors.log for the web server) in the certificate management area of the web server the root shows up as a 'client root', whatever that means. So what fields must be set in a root? I might be missing some. What fields must be set in a server certificate? I tried looking in the email archives but none of the searchable archives helped much looking for this. Pardon me if this has been answered before. Note: there's no "download the archive as one big slab of text" archive, so I couldn't do extreme search techniques... __ OpenSSL Project http://www.openssl.org User Support Mailing List[EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
Re: localhost certificate (no, really!)
the host name would not resolve uniquely. the host name wouldn't represent the business. other parts of the DN (state, organization, etc.) would be unique, but the common name wouldn't. IMO your application should be able to handle multiple hosts, or not care what host if it's the security of the SSL connection.

Re: Looking for ASN.1 specification for PKCS7
download the pkcs7 documentation. also, look in the PKIX documentation. when we did the early IPsec work we found there were some missing pieces, I believe RSA eventually published all of it somewhere.

Re: DLL problem
Depending on how you install VC you can have issues with threading. If you compile for multithreading but have the single thread only version of VC loaded, I recall problems...

In particular, I don't remember specifying anything about threads (although the makefile ms\ntdll.mak does include the MD flag). The library is used in multithreaded code and has not had any problems (as S Henson says, the calling code must also be compiled with the MD flag). However, I do call CRYPTO_set_locking_callback with a routine that I lifted from mttest.c (according to the comments in my code).

Re: Millenium and 37 bug
you should be able to go to at least 2049, as the PKIX limit is around 2050. I know some vendors have tested this.

We tried (just because we were fed up with test certificates expiring) and found that we couldn't get past 2037, presumably because that's when "unix time" runs out of bits (although this was on NT). Presumably the fix is to link against a library which has t_time defined as something larger (or at least unsigned) - does such a library exist? As CRLs and certificate chaining become more popular, it seems, to me, that having long-lasting certificates will be more important - so I don't think ignoring the problem is the best solution Andrew __ OpenSSL Project http://www.openssl.org User Support Mailing List[EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED] __ OpenSSL Project http://www.openssl.org User Support Mailing List[EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
